摘要： In an ultrasound imaging system, the mean velocity of a fluid flow, variance of velocity of the fluid flow and energy value of Doppler ultrasound signals from the flow in response to transmitted ultrasound are first estimated from autocorrelation values of the signals to form a set of parameters for a corresponding sampling time or a corresponding sampling location. An averaging process is then performed on two sets of the estimated parameters corresponding to a plurality of different sampling times in temporal filtering or on two sets of the estimated parameters corresponding to a plurality of different locations in spatial filtering. The filtered parameters are then compared to thresholds in a discrimination process to reject noise and clutter.

摘要： A filter for filtering digital image data includes a timing circuit to convert received line sync signal and a received page sync signal to a new line sync signal and a new page sync signal and a N.times.M filter to filter digital data based on the new line sync signal, the new video valid signal and the new page sync signal. N is a value representing a filter dimension in a slow scan direction, and M is a value representing a filter dimension in a fast scan direction. The timing circuit causes the self-timed image processing device to output (N-1)/2 scanlines of unfiltered digital image data after the received page sync signal indicates an end of an input page.

摘要： A system for filtering an image during data compression using a standard JPEG compression/decompression chip typically requires a separate spatial filter external to the chip. The spatial filter is composed of numerous shift registers, flip-flops, multipliers and at least one adder. In contrast, an image filtering system which filters in the frequency domain using the inventive JPEG compression chip modified for filtering in the frequency domain does not require the separate spatial filter and its many components. The modified JPEG chip includes a raster to block converter which converts an image signal into 8.times.8 blocks, a DCT processor which converts the 8.times.8 blocks into DCT coefficients, a multiplier which generates filtered DCT coefficients by multiplying predetermined filtering coefficients times the DCT coefficients, a quantizer which generates quantized blocks to a predetermined level stored in a visibility table by quantizing the filtered coefficients, a zigzag scanner which generates a vector having the same number of elements as the quantized blocks, a run-length coder for determining the appropriate run-length according to entropy encoding received from a preloaded Huffman table, and a variable length code packer/unpacker for compressing the entropy encoded vector. A block to raster converter is included to reformat decompressed data.

摘要： Image processing apparatus is described for filtering a digital representation of a raster scanned image into a plurality of sub-bands in the two-dimensional spatial frequency domain, the resolution of the raster scanned image in a first direction (usually the horizontal direction) being greater than the resolution of the raster scanned image in a second direction (usually the vertical direction). The image processing apparatus has a decimation filter means comprising a number of multi-tap digital decimation filters for spatial filtering in the first and second directions. The mean of the filter lengths of the filters used for filtering in the first direction is greater than that of the filters used for filtering in the second direction. Complementary interpolation apparatus for reconstructing the image from the plurality of sub-bands is also described.
